Plankton Images from East Australian Current Eddy Study

High-resolution plankton images were captured during a 25-day research voyage in the East Australian Current system in late 2023. The dataset is hosted on the EcoTaxa platform and includes associated metadata for taxonomic classification. Data collection was led by researchers from the CSIRO Marine National Facility aboard the RV Investigator.

Use Cases

• Train image classification models to identify planktonic organisms using the high-resolution PNG images.
• Assess biodiversity metrics by analyzing the taxonomic labels and metadata associated with each image.
• Validate and improve automated classification accuracy, particularly for the Radiozoa group where inconsistencies are noted.
• Correlate plankton community composition from the images with physical oceanographic data from the East Australian Current voyage.

Strengths

• Images are described as high-resolution, supporting detailed taxonomic analysis.
• Dataset is dynamic and undergoing active validation, with plans to increase the number of available images.

Limitations

• Classification accuracy is noted to have inconsistencies, particularly within the Radiozoa group.
• The exact number of images, rows, and sample size is unspecified.
